简介
The CD59 protein is a potent inhibitor of the complement membrane attack complex (MAC) and binds to assembled C8 and/or C9 complement, preventing the incorporation of multiple C9 copies that are critical for permeability pore formation. Its species-specific inhibitory effects extend to T cell activation, complexing with protein tyrosine kinases for signal transduction. CD59 Protein, Human (HEK293, His) is the recombinant human-derived CD59 protein, expressed by HEK293 , with C-6*His labeled tag.

Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Protein Description
CD59, a glycosylphosphatidylinositol (GPI)-anchored membrane protein, plays a crucial role in the regulation of the complement system, which is a vital part of the immune response. It inhibits the formation of the membrane attack complex (MAC), thereby protecting host cells from lysis by complement proteins. Abnormal expression or dysfunction of CD59 has been linked to various pathologies, including autoimmune diseases, cancer, and infectious diseases. Consequently, researchers have focused on the potential therapeutic applications of CD59, exploring its role not only in complement regulation but also in modulating immune responses. Recombinant CD59 proteins are being developed to better understand its functions and mechanisms, to design novel therapies that can enhance immune protection in patients with compromised immune systems, or to inhibit complement activation in conditions characterized by excessive complement activity. Additionally, CD59 is being investigated as a possible target for drug delivery systems and vaccine development. The study of CD59 recombinant proteins also provides insights into the structure-function relationships of membrane proteins, advancing our understanding of cell biology and immunology. Overall, the research on CD59 recombinant proteins holds promise for innovative therapeutic solutions while contributing to the broader field of immunology and molecular biology.
